Hi BubBub and welcomed to this challenge!!
First of all, I measured myself yesterday night and I was 79cm arround my waist line. Then, I started the workout with the bottle of water and felt my arm muscles working and my tummy muscles too. Felt good, as I'm not used to doing any exercise...
As I'm writing this, I'm realizing that it's been a long time since I last weighed in, so I'm going to do it tonight and update my profile too.
See you tomorrow!
Susanne.
